Thanks Lobo, the RD is now back in the garage, now the 400/4 is in rolling chassis mode there is more room, it only lives in the conservatory when on SORN in winter, I got a new rear brake seal and got it through the MOT then the new seal started to weep, fortunately I was monitoring it so it didn't cause any damage to the paint like the first time, how hard is it to get a decent 5/8 master cylinder seal ? I live just south of Preston in Walton-le-Dale.
